Sewage treatment unit capable of effectively reducing COD suspended solids (SS)

Abstract

The invention discloses a sewage treatment unit capable of effectively reducing COD suspended solids (SS). The sewage treatment unit comprises a filter, a hydraulic workstation, an electric cabinet, a sewage pool, a sludge sump and a clear liquid pool, wherein a thrust plate and a press plate are arranged on the filter, a filter plate and a filtration fabric are arranged between the thrust plate and the press plate; a hydraulic cylinder base is arranged on the filter, and a hydraulic cylinder is arranged on the hydraulic cylinder base; a cross beam is arranged on the filter, and a drawing plate unit is arranged on the cross beam; a first three-way pipe is arranged between a liquid inlet and the sewage pool, the first three-way pipe is connected with the sludge sump, a sludge discharge valve is arranged between the first three-way pipe and the sludge sump, a second three-way pipe is arranged on a water outlet channel, one end of the second three-way pipe is connected with a backwashing pump, the other end of the second three-way pipe is connected with the clear liquid pool, and a water outlet valve is arranged between the second three-way pipe and the clear liquid pool. The sewage treatment unit has a function of continuously filtering, has a filtering function on sewage in combination with the filter, is large in filter plate filtering area, has an effect of increasing water discharge capacity and can be used for effectively reducing the content of COD suspended solids (SS).

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment device for effectively reducing COD suspended matter (SS). Background technique [0002] Industrial sewage refers to the sewage and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants produced in the production process. With the rapid development of industry, the types and quantities of sewage have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Therefore, for the protection of the environment, the treatment of industrial sewage is more important than the treatment of urban sewage. With the rapid development of the economy, people's living standards are constantly improving, and the requirements for the ecological environment are al...

Problems solved by technology

Its main feature is that it occupies a small area and has a large pressing area. Its disadvantages are that the water outlet channel is not smooth and works intermittently, so it cannot be used in the process where water filtration is the main purpose.
